5. SYSTEM MAINTENANCE MENU SCREENS
5.01
Figure 6 is the Maintenance Terminal MAIN
MENU Screen. Its eight sub-menus provide
many useful provisioning, test and monitoring tools.
Figure 7 shows the HLU-231 List 6D SPAN STATUS
Screen.
5.02
Figure 8 shows the SET CLOCK menu. Both
the Time and Date are set with this menu. Set
the hours and minutes, using the military (24-hour)
convention. Setting the seconds is optional. Enter the
date in the sequence and format shown. List 1 HRU-
412 units having software versions 6.4 and above, and
all List 6, List 7 HRU-412 units can also be set to the
same time and date as the HLU-231 List 6D by entering
a U to the “Update Remote” query. All time information
is lost when power is removed. The last date, however,
is retained in NVRAM and reappears when power is
restored.
5.03
Figure 9 shows the SYSTEM SETTINGS
Screen. All 14 user options can be set from this
screen. To change any option, enter its character key
which is shown inside the parenthesis within each
parameter description. This causes the screen to
refresh with the new parameter. After all parameters
have been selected, press E (Exit) then C (Confirm).
The newly selected parameters are now activated.
5.04
Figure 10 shows the LOOPBACK MENU
Screen for non-Doubler applications.
Loopbacks NLOC, NREM, CLOC & CREM are available.
5.05
Figure 11 shows the PERFORMANCE DATA
screen for non-Doubler applications. Both the
Errored and Unavailable Seconds for both HDSL loops
and each T1 input are listed at 15-minute intervals over
a four hour time interval. Earlier & later data, in four-
hour chunks on six different screens, can be accessed
by pressing P (Previous) or N (Next) respectively. All of
the counters can be set to zero by pressing C (Clear)
from the HLU-231 List 6D SPAN STATUS Screen
shown in Figure 7. Note that since the HLU-231 List 6D
is considered the master module, this clears
all
performance data screens at both the HLU-231 List 6D
& the HRU-412. The RS-232 terminal interface at the
HRU-412 does not allow the counters to be cleared.
5.06
Figure 12 shows the 7-DAY PERFORMANCE
HISTORY Screen. The “Errored Seconds” and
“Unavailable Seconds” for both HDSL loops and each of
the two DS1 inputs are listed for the current and
previous seven days. All of the counters can be set to
zero by pressing C (Clear) on the HLU-231 List 6D
SPAN STATUS Screen (Figure 7). Note that since the
HLU-231 List 6D is considered the master module, this
clears
all performance data screens at both the HLU-231
List 6D & the HRU-412. The RS-232 terminal interface
at the HRU-412 does not allow the counters to be
cleared.
5.07
Figure 13 shows the ALARM HISTORY Screen
for non-Doubler applications. The alarms are
defined in Section A Paragraph 4.01. The “First” &
“Last” columns contain the time & date stamp of the first
& last occurrence of each alarm. The “Current” column
shows the status of each alarm. The “Count” column
lists the number of times each alarm occurred. All the
data can be cleared by pressing C (Clear). The
maximum non-overflowing count is 999.
5.08
Selection “H” from the main menu allows the
Circuit ID # to be set. It is limited to 24 alpha-
numeric characters. It, like the system settings, is
stored in NVRAM and thus remains when power is lost.
Note that the Circuit ID # is not available at the HRU-412
Maintenance Port.
